CRUPPER FORMER-AND STRETCHER.

EiPECIIE'ICATION forming part of Letters Patent No. 303,372,6iated August 12,1884,

Application filed May 23, 1881. (No model.)

F0 all whom it may concern.-

Be it known that I, LA FAYETTE HARTSON, a citizen of the United States, residing at \Vyoming, in the county of Jones and State of Iowa, have invented a new and useful Orupper Former and Stretcher, of which the following is a specification, reference being had to the accompanying drawings.

Myinvention relates to a device for forming cruppers for harness 5 and it has for its object the production of a device of this character which shall be simple in its construction and effective in its operation, and one which will be capable of producing a crupper which shall possess superior advantages in point of shape or form, and one that will preserve the same.

WVith these ends in view,the invention consists in the combination,with aforming-block, of a clamp for receiving the ends of the crupper or means for stretching said crupper.

The invention further consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a crupper-former constructed in accordance with my invention. Fig. 2 is a plan Fig. 3 is a longitudinal vertical section. Fig. 4 is a perspective view of one of the clamping-plates detached, and Fig. 5 is a modified form of clamping-plate.

. In the accompanying drawings, in which like letters refer to corresponding parts in the several figures, A represents a frame or table, which is preferably cast, and consisting of the side rails, a, connected at one end'by means of a cross-bar, b, and supported at said end by means of legs a, which are also cast with said sides and crossbar. At the other end of the table is provided a forming-block,which is cast with the table or frame, said block B,

in the upper end of the head-mock. atone end,

- as shown at a and in the rodor bar I) at the other end, theend supported by bar I) passing through the same, and being bent to form a crank or handle, (I. At the points at which this feed-screw has bearing the same is made smooth, so that it will turn loosely therein and will not movein any direction other than to be turned or revolved. Upon this feedscrew is mounted a clamp, E, the lower section of which has a screw-threaded opening to receive the feed-screw which works therein. Upon the surface of the section 6 of the clamp E is provided a series of corrugations, f, while just in rear of said corrugationsand upon the sides of the section 6, are provided two upwardlyprojecting brackets, having perforations or openings h. The upper clamping-plate, i, is provided on its under side with a series of corrugations similar to those on the lower plate, and is also provided on its rear side with a lug, J, which has an opening, Jr, said lug, fitting between the brackets g, and being removably secured therein by means of a pin, 70,

passing through the openings of said lug and brackets. Upon the upper clamping-plate is provided a screw-threaded opening, I)".

G represents a set-screw for adjusting or tightening the clamping-plates upon the ends of the crupper when in operation, said screw turning in the opening b and bearing on the lower clamping-plate, said set-screw being preferably formed at its end with a crank handle, as shown.

In Fig. 5 I have shown a modification in which two rearwardlyprojecting arms are provided on the lug j, between which arms 'is pivoted at the rear endthereof a cam-lever,

m, for clamping the two sections together.

In forming cruppers, the same are first wet and doubled in the usual manner, and are then placed upon the forming-block. The clamp being opened, the ends arethen placed between the same and held there by means of the setscrew. The feed-screw is then operated by means of the handle, and as it is turned the clamps are drawn rearwardly, thus forming the crupper at the same operation.

By the employment of my improved former and stretcher, a crupper, when once made, will preserve its shape and form, and will not Too give or stretch in use, at the same time producing a crupper much neater in appearance than those made by hand.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, iS

1. In a erupper former and stretcher, the

combination, with a frame or table having a forming-block cast integral therewith at one end, and a feed-screw mounted to turn loosely in said frame or table, said feedscrew being provided with an opel'atinghandle, of a clamp consisting of two sections pivotally connected, and a crank-screw for clamping said seetions,said crank-screw working in a screw thre aded opening in the upper of said sections, and bearing upon the upper side of the lower section, sub stantially as set forth.

2. The herein-described crnpper former and stretcher, consisting of a frame or table havi ng a forming-block cast integral therewith at one end, a iced-screw working in said frame, a clamp consisting of two sections pivotally connected, the bottom section being provided with upwardly-proj ectin g perforated brackets, and the upper section having aperforated lug fitting between said brackets and held in place by a rod, said sections being provided on their meeting faces with a series of corrugations, and a set-screw for adjusting or clamping said sections, substantially as set forth..

3. The combination, with a frame or table having a crupper-forming block cast integral therewith at one of its ends, of a feed-screw Working in said frame or table, and clamping plates mounted on and actuated by said feedscrew to stretch and form the crupper, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in 40 presence of two witnesses. I

LA FAYETTE HARTSON.
